Technical knowledge：Introduction to EMC Laboratory Site: Conducted Susceptibility (CS) Section
I. Test Items
The conducted immunity test is used to evaluate the anti-interference capability of equipment or systems against electromagnetic disturbances from radio frequency (RF) transmitters. During the test, the equipment is coupled to the RF field through at least one connecting cable (such as power lines, signal lines, ground lines, etc.) to verify whether it can maintain normal functions and performance under electromagnetic disturbances and ensure compliance with relevant electromagnetic compatibility (EMC) standards.
II. Test Objectives
The conducted immunity test aims to ensure the stable operation of equipment in a real electromagnetic environment. By evaluating its conducted immunity, electromagnetic interference issues that may cause equipment failure or performance degradation can be identified and resolved, thereby optimizing the electromagnetic compatibility of the equipment.
III. Test Principle
For low-frequency (150 kHz - 80 MHz/230 MHz) RF signals, due to their wavelengths being much longer than the EUT's dimensions, the interconnection cables of the EUT (such as power lines and signal lines) are more likely to act as antennas to receive electromagnetic fields than the device itself. Therefore, the low-frequency part of the RF immunity test adopts a conducted test method.
During the test, electromagnetic radiation of multiple frequencies and power levels is applied to the equipment in accordance with the standard requirements to evaluate its immunity to interference under various conditions.
